Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms ( biodiversity ) and abiotic properties such as nonliving things like water or soil ...
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
The loss of biodiversity may not directly affect humans, but the indirect effects of losing many species as well as the diversity of ecosystems in general are enormous. When biodiversity is lost, the environment loses many species that perform valuable and unique roles in the ecosystem.
Exploitation of Earth’s natural resources and climate change are devastating the planet's biodiversity 5 ways humans are destroying biodiversity
Attenborough says that wildlife trade and other human interaction with animals cause viruses to spread, and can be initial causes of pandemics. He attributes the COVID-19 pandemic to human expansion into areas of Yunnan, with the virus perhaps spreading from bats to Wuhan via humans or animal markets. Experts warn that current human activity ...
There have been many claims about biodiversity's effect on the ecosystem services, especially provisioning and regulating services. [138] Some of those claims have been validated, some are incorrect and some lack enough evidence to draw definitive conclusions. [138] Ecosystem services have been grouped in three types: [138]
Population bottleneck followed by recovery or extinction. A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, speciocide, widespread violence or intentional culling.
An ecosystem does not necessarily offer all four types of services simultaneously; but given the intricate nature of any ecosystem, it is usually assumed that humans benefit from a combination of these services. The services offered by diverse types of ecosystems (forests, seas, coral reefs, mangroves, etc.) differ in nature and in consequence.
